A man said, "Messenger of Allah, I did not realize, and I slaughtered before stoning."He replied, "Stone, and there is no harm."Another said, "Messenger of Allah, I shaved before slaughtering."He replied, "Slaughter, and there is no harm."He was not asked that day about anything done before or after its proper order except that he said, "Do it, and there is no harm."
حدثنا عبد الرحمن حدثنا مالك بن أنس عن الزهري عن عيسى بن طلحة
أن رجلا قال يا رسول الله لم أشعر نحرت قبل أن أرمي قال ارم ولا حرج قال آخر يا رسول الله حلقت قبل أن أنحر قال انحر ولا حرج فما سئل يومئذ عن شيء قدم ولا أخر إلا قال افعل ولا حرج
